I was thinking to start with the Zone Diet, a few years ago I was on
Atkins and I feld really well and was losing quiet some weight.
the problem started once when I was reading too many anti Atkins
articles and left the diet.

If you did well on Atkins and the reasons you quit are known
to be invalid, why not go back to what worked?

Thing is despite my weight I'm not really a big eater and with The Zone
I have to calculate the blocks all together in order to get the right
amount of proteins etc.
Do I have to eat that many blocks as it's calculated?, or can I eat less?
Is there some kind of program that can calculate the amount of food that
fits in the desired amount of blocks?

I don't know The Zone well enough to answer your questions,
but if your food takes you below some number of protein grams
it becomes a problem. So I think it depends on how much
less you mean.

I know people can be against it, but that's with any diet, when I was
on Atkins the doctor never noticed any ingrease of my clorestoral levels,
infact it was quiet the opposite.

Which goes back to why the writings on anti-Atkins folks are
not valid so should be ignored.

Sorry but The Zone isn't popular enough to get a lot of traffic
so I haven't learned enough about it to give better answers. It
seems a fine program when followed per its directions.
